IMPROVEMENT IN FASTENING DEVICES FOR FURNITURE.

Specification forming part of Letters Patent No. 192,293, dated June 19,1877 application filed April 23, 1877.

To all whom it may concern:

Be it known that I, HENRY SGHAAF, of St. Louis, in the county of St.Louis `and State of Missouri, have invented an Improved FasteningDevice, &c., of which the following` is a specification This inventionis an improved fastening device for cabinet-makers uses in themanufacture of household and office furniture, storeittings, tc. Assuch` fastener it is applicable to unite the top and bottom to the bodypart, composing a wardrobe, or a desk, bureau, or the parts of abedstead, dto. By its use the screws, wrenches, and pieces of wood now'used for these purposes are obviated, and the said parts of furniturecan readily be locked together or readily detached, as the case mayrequire.

My invention is also applicable as a window-sash fastener, and for latchpurposes.

Of the drawing, Figure 1 is a side elevation of my improved fastener asapplied for use and when in a locked condition. Figs. 2 and 3 arerespective cross-sections taken on line Xl X1 and X2 X2 of Fig. l.

My fastener consists, essentially, of the casing parts A A', thesemcircle bolt B, and the lug-plate U. (See figures.) The casing part Ais simply a plate cast to have the lugs at a. (See figures.) The casingpart A isa like plate, but cast to contain the operating-bolt. For thispurpose the part A' has its surrounding edge to be a projecting rim, a',and at b to have a center lug, `all shown in figures. The projecting rima' forms the chamber part b1, for the bolt to operate in and out, andalso serves, at proper points, to guide the operating-bolt. Likewise theIugb serves as a guide,

and also to secure the bolt in operating condit-ion. At b2 the part A'has a slot, curved and elongated to suit the travel of the knob thatoperates the bolt. (See Fig. l.) The bolt B, as shown in figures, is aplate made semicircular, its edges at b3 being beveled to suitcorresponding bevels made in the contiguous parts ofA'. (Sec figures.) Cis the lug-plate, the lug c thereof being an arc to conform to the partof the bolt. (See Figs. l and 2.) D D' represent the parts of furnitureto be united. The lug-plate O is screwed to the part D. The casing partsA A', containing the bolt B, are screwed to the part D. I The samescrews unite the parts A A' to the part D.

rIhe fastener having its parts thus secured in relative operativecondition, it is simply uccessary to cause the bolt B to engage thelug-plate C, as shown in Fig. 1, to lock the parts of furnituretogether. As is apparent, this is done by a part rotary movementimparted to the bolt B. The reverse movement will cause the bolt B todisengage from the lug-plate C, disunitingthe parts D D', the bolt inunlocked condition being then entirely contained in the casing parts AA'.

A fastening device of the character herein shown and described,consisting of the casing parts AA', the bolt B, and lug-plate G, allsaid parts being constructed and combined to operate substantially asset forth.

In testimony of said .invention I have hereunto set my hand.
